Answer:

4

Step-by-step explanation:

Given

when y = 2 then

2(x+y) = 12

2( x + 2) = 12

(x +2) = 12/2

x + 2 = 6

x = 6 - 2

x = 4

hope it helps :)

Answer: 4

Step-by-step explanation: if 2 times y(2) is 4 what plus 4 equals 12...8 right? but you have to take 2 and multiply it by 4 in order to get 8. So the answer is 4. Hope this helps! :)

Tom determines the system of equations below has two solutions, one of which is located at the vertex of the parabola. equation
BabaBlast [244]
Y = ( x - 3 )² + 4
Vertex of the parabola:  ( 3, 4 )
y = - x + b
4 = - 3 + b
b = 7
Equation 2: y = - x + 7
( x - 3 )² + 4 = - x + 7
x² - 6 x + 9 + 4 = - x + 7
x² - 5 x + 6 = 0
x - 2 x - 3 x + 6 = 0
x ( x - 2 ) - 3 ( x - 2 ) = 0
( x - 2 ) ( x - 3 ) = 0
x 1 = 2,  x 2 = 3
y 1 = 5,  y 2 = 4

Find the slope of the line whose equation is 7x - 2y = 4. 7/2 -2 4/7
Nookie1986 [14]
To find the slope, we must put the equation in y = mx + b form, and m represents ur slope.

7x - 2y = 4....subtract 7x from both sides
-2y = -7x + 4 ...now divide both sides by -2
y = (-7/-2)x + (4/-2)
y = 7/2x - 2....now we have it in y = mx + b form, and since m is ur slope, ur slope in this equation is 7/2.
